A take on QEMU

In one sentence, QEMU is an open source CPU and system emulator. As an emulator or virtualizer, QEMU has two modes of operation: it can emulate a full system so that an operating system can run on top of it (system emulation), or it can just emulate a CPU in a mode called user emulation (this mode is Linux specific), so that binary applications can run on a different CPU that they have been compiled for.
